POWER BI - THE ARCHITECTURE

Power BI Architecture: A Comprehensive Guide to Building Effective Data Analytics Solutions     Understanding Power BI Architecture: Power BI's architecture comprises four main components, each playing a pivotal role in the data analytics process: Data Sources:   Power BI connects to a wide range of data sources, including databases, cloud services, Excel files, web services, and more. This versatility enables organizations to consolidate their data from various systems into a single dashboard. Data Transformation:   Once the data is sourced, it undergoes transformation and cleaning processes to make it suitable for analysis. Power BI's Power Query Editor provides a user-friendly interface to manipulate, filter, and shape data according to specific requirements. Data Model:   The heart of Power BI's architecture lies in its data model, whic...

TOUCH PLATE BASED DOOR BELL

Title:  Touch plate based door bell  Circuit:  Components: IC 555 Resistors: 1 M, 100k, 330 ohms Transistor: BC547  PN2222A Capacitor: 10n 1 Copper plate : as touch plate. A 6v battery An LED / Ic UM66 Description: This is the simple circuit for touch plate based security system. In this project what basically done is, circuit detects stray voltages produced by mains voltage and electrostatic built  up in the room.If sufficient static voltage is detected by the plate then chip will charge up. Transistor BC 547 or PN2222A is used basically to increase the sensitivity.In place of led just connect IC um 66(melody IC). Applications: In homes, of course. This can be specially used in places like hospitals, when patients need to call doctor by himself.
